It's a novel theory but I doubt this was the motivation.

Could 'town-gown' conflict be a possible motive i…: https://youtu.be/6U1FucSaiOE

I lived there for 11 years. My best friend still lives there. The university is a pretty well integrated into the town (which is very small). There was no townies vs. the university feeling when we lived there. I didn’t watch the video, but I can’t imagine this being plausible.

I’m betting the person that killed them is someone they knew. When I was in ver school one of the student a few classes behind me was stabbed, and later died. No forced entry, several theories about violent classmates, they think she knew her killer. But no one was ever charged.

I think it was somebody they knew.

I'm surprised by the investigation's lack of progress.

I have wondered if its a connection to the fraternities and sororities somehow - either an anti-Greek thing, or someone who knew them all through that. I don’t remember feeling the Greek system was all that huge on campus (compared to some of the other Universities we’ve been at). A lot of students went home after this happened, and I don’t know how many came back - I think they have done their best to support people online if they felt uncomfortable. I imagine they are paying attention to what students left and maybe won’t come back - assuming some of those are potential suspects.
